I'd love to try my hand at all of the metagames, but I have the most experience with 4th and 5th gen.
I have no Pokemon battling legacy, VGC or otherwise, but that's one reason I want to participate in this. I'm not bad or anything, I'm just unknown to the community. The main thing that sets me apart from most Trainers is that I do a lot of experimenting with odd Pokemon and sets. I don't like the idea of using whatever the current metagame offers; I would rather battle with my own ideas that still work. If I had to quantify my playstyle, I guess I would have to say that I prefer a kind of all 'round style. My most hated style is stall (freaking Toxic/Protect/Protect/Protect, Flinchfag Jirachi, and Wish/Protect).
